python - 尝试导入 sklearn 模块时出错 : ImportError: DLL load failed: The specified module could not be found

Question

我尝试为机器学习项目执行以下导入:

from sklearn import preprocessing, cross_validation, svm
from sklearn.linear_model import LinearRegression

我收到此错误消息:

Traceback (most recent call last):

    from . import _iterative
ImportError: DLL load failed: The specified module could not be found.

请帮助我尝试了所有方法，但没有任何效果。我也尝试了这些解决方案: ImportError: DLL load failed: Le module spécifié est introuvable

ImportError: DLL load failed: The specified module could not be found

Answer 1

这一行指向 scipy。

从 scipy.sparse.linalg 导入 lsqr 为 sparse_lsqr

你可以试试:

pip 卸载 scipy

pip 安装 scipy

尽情享受吧!
